Khairul Enam 1 Military Institute of Science and Technology, Mirpur Cantonment, Dhaka, Bangladesh In the past decades, there have been a great number of studies concerning the flow around circular cylinders. Depending on the researcher's interests, these studies investigated various perspectives of the flow phenomenon, including the pressure distribution, force coefficients, vortex shedding, Strouhal numbers, flow patterns, etc. Most of these investigations were conducted by means of wind tunnel experiments, and only a few were carried out with full-scale measurements. These previous research work is reviewed in this paper. Since the mean drag and lift coefficients are of the most interest in these study, the data regarding these parameters constitutes the majority of the review work as well. http://pubs.sciepub.com/ajme/5/3/3/ajme-5-3-3.pdf tandem cylinder downstream wave critical spacing critical regime drag coefficient progressive transition
